摘要： A binarizer binarizes a video signal VD1 inputted from an A/D converter and a video signal VD2 outputted from a line memory using an average luminance value LU fed from a detection window video signal processor as a threshold value, to output a binary pattern BI. A reference pattern generator generates a plurality of reference patterns RA. A first pattern matching angle detector compares the binary pattern BI with each of the plurality of reference patterns RA, to output the angle of the reference pattern RA which matches with the binary pattern BI as angle information PA. A detected isolation point remover 4 outputs angle signal AN when the angle information PA has continuity.

摘要： A plasma display having a discharge cell, the emission efficiency of which is improved by generating first and second discharges with one sustaining pulse. A first discharge is generated by increasing a voltage up to a maximal value through a LC resonance formed by a recovery coil and a panel capacitor. A second discharge is generated by connecting the panel capacitor to a power supply when the voltage falls a predetermined amount below the maximal value, thereby increasing the voltage to a predetermined level above the maximal value.

摘要： A pseudo-contour noise detecting device for detecting pseudo-contour noise is provided. The pseudo-contour noise is embodied as contour lines appearing spuriously in a motion picture displayed such that a gradation display is performed by using a plurality of weighted subfields into which one field of an input image, including a plurality of pixels, is divided. The device includes a pseudo-contour noise calculating unit in which, a logic operation is performed, for each subfield, on each pixel of at least a portion of the input image using a value of the each pixel and values of at least one of the pixels surrounding the each pixel. Further, a value corresponding to an amount of pseudo-contour noise is calculated according to a number of subfields in which a difference is detected between the value of the each pixel and the values of the at least one of the pixels surrounding the each pixel.

摘要： A display apparatus creates, for each image, a number of subfields Z from a first subfield to a Zth subfield in accordance with a Z bit representation of each pixel, a weighing value for each subfield, and a number of gradation display points. The display apparatus detects a peak image brightness level and an average image brightness level. A weighing multiple including a positive integer part and a fractional part is determined based on the peak image brightness level and the average image brightness level. The weighing multiple is multiplied by the weighing value of each subfield to obtain a product capable of having a positive integer part and a fractional part. An integer value near the product is defined as a number of drive pulses for each subfield. The weighing multiple is increased as the average image brightness level decreases and as the peak image brightness level increases.

摘要： A display apparatus has an adjusting device, which acquires image brightness data, and adjusts a weighting multiplier N on the basis of brightness data. The weighting multiplier N takes not only a positive integer, but also a decimal fraction numeral. In accordance with this, even if weighting multiplier N changes, an abrupt change in brightness does not occur, and a person watching the screen is not left with a sense of incongruousness.

摘要： In an image display apparatus, a video signal is divided for each field into a plurality of sub-fields, each of which is weighted according to the duration of time or number of pulses. The plurality of sub-fields are temporally superimposed for display, so that a grayscale representation is provided. A video signal for the current field is delayed by one field, and output as a video signal for the previous field. Based on the video signal for the current field and the video signal for the previous field, a luminance gradient of an image is detected. A difference between the video signal for the current field and the video signal for the previous field is calculated. Based on the calculated difference and the detected gradient, the amount of motion of the image is calculated by a detecting circuit. Based on the calculated amount of motion of the image, dynamic false contours are reduced by an image data processing circuit.
